Best pillow I've ever had
Size: Queen (Pack of 1)
I don't really write reviews but holy buckets, Batman. This pillow is legit. Back, neck, and shoulder pain is nothing new for me; I've had scoliosis since I was a kid and hyperflexibility in my neck since birth leading to frequent muscle spasms that have caused me to miss work. Guys. This pillow. It is the most comfortable pillow I've ever had. Like, my neck doesn't hurt and I genuinely didn't remember what that felt like. It's simultaneously supportive and soft and it doesn't sink in. The instructions are super clear to understand and the pillow fluffs up no problem if it gets a little flat. This is a game changer for me and I so hope anyone who buys this has the same experience.

I highly recommend this pillow, it’s great for someone with neck or back problems.
Size: Queen (Pack of 1), Size: Queen (Pack of 1)
I absolutely love this pillow! When it says it’s adjustable it definitely means that. When you first get it, it’s hard to believe that it’s going to be anything but put it in the dryer for a few minutes and it becomes so large. You will definitely have to remove some of the stuffing unless you like a really large fluffy pillow. The stuffing is high-quality and once it has been put into the dryer it becomes a fibrous type material that can be fluffed over and over and go back to the same size. It seems to be a high-quality cover on the outer portion and is thick and has a slight cooling affect. It has a separate cover on the inner portion covering the foam stuffing. I ordered this because I have neck problems and it has been super comfortable for me because I’m able to adjust it multiple times depending on my needs for the particular night when I lay down. Having the extra stuffing means that if the pillow does happen to go flat I can always add the extra that I took out when I received it. It did have a slight odor when it first came, but after putting it in the dryer, it went away immediately. I do think that’s only due to the plastic that it’s shipped in not anything with the pillow. I think this pillow is well worth it price and I would highly recommend it for anyone that is a side or back sleeper or has any type of neck problems.

Amazing!
Size: King (Pack of 1)
Such a great pillow I’m buying another one! You can add or subtract stuffing to your liking. It’s really nice quality, quilted and soft. Best pillow ever. Super comfy and great sleep. Pretty firm with all the stuffing. Perfect the way it came with stuffing on the side. My husband loves it and now I want one.

Totally worth the money

Right off the bat, the packaging is absolutely adorable and felt like I was buying a premium product. I love that this pillow is adjustable and as a side sleeper, I needed a pillow that is both firm and supportive of my neck. This hits all the boxes. We will be buying more of these for our bed!

Excellent pillow

This is a great pillow!! I ordered this for my elderly mother who wanted a softer pillow. She absolutely loves this one. It’s supportive, keeps her cool also keeps its shape. I love that it came with extra stuffing so you can customize it. Well worth the price!!
